An accurate way of estimating the risk of a fetus having Down Syndrome or other chromosomal abnormalities is carried out from 11.2 to 13.6 weeks and depends on the age of the mother, amount of fluid behind the neck of the fetus, presence or absence of the fetal nasal bone and the presence or absence of any physical abnormalities. The nuchal translucency scan is not a diagnosis but can identify those babies that may be at risk of having a chromosomal abnormality such as Down Syndrome.
The fluid at the back of the foetal neck can give information that may raise the suspicion of a problem. The measurement of this fluid is taken at a very specific time in the pregnancy between 11.2 and 13.6 weeks gestation.
Nuchal Translucency (NT) is only a screening and is effective when taken in combination with:
• Maternal age
• Ultrasound at 11.2 – 13.6 weeks
• An accurate measurement of the nuchal translucency
This method of screening increases the detection rate of Down syndrome and other major chromosomal abnormalities. Sonographers and doctors need special training and high resolution ultrasound equipment to perform it correctly. They must be certified by the Fetal Medicine Foundation in London UK, the organization that provides the international standards and software that enable us to evaluate your baby’s risk

* The level of two hormones (b-hCG and PAPP-A) in the Mother’s blood can be assessed for additional accuracy. We do not offer this at our centre.
